The new Composition Animation effects available in Windows 10 make it easy to create simple animation effects for XAML controls. For example, here's a simple example that applies a scaling effect to a Button when the user's mouse pointer moves over it.
Here's the XAML:
<Page
x:Class="UWP_Animation.MainPage"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
